There are some useful extensions to Tk written in Tcl. For example, 
there is tablelist - a tree widget or multicolumn listbox in pure Tcl. 
By passing it to the Tcl interpreter, you can wrap it up for Python - 
that's what Kevin Walzer did at

It would take many man-month to reproduce this thing in Python.

Another example is the file open dialog (import tkFileDialog). On 
Windows and OSX, it uses the native variants, but on X11 it uses a very 
outdated, ugly and hard to use thing bundled with Tk. With just a few 
lines executed by some Tk.eval('source myfixes.tcl'), I overwrite this 
dialog box with the one created by Schelte Bron:

For reference, here is myfixes.tcl:

lappend auto_path [file dirname [info script]]
if {[tk windowingsystem] == "x11" } {
	package require fsdialog
	interp alias {} tk_getOpenFile {} ttk::getOpenFile
	interp alias {} tk_getSaveFile {} ttk::getSaveFile
	interp alias {} tk_chooseDirectory {} ttk::chooseDirectory
